'Bless' in the Bible

Then David returned to bless his household. And Michal the daughter of Saul came out to meet David, and said, How glorious was the king of Israel to-day, who uncovered himself to-day in the eyes of the handmaids of his servants, as one of the vain fellows shamelessly uncovereth himself!

now therefore let it please thee to bless the house of thy servant, that it may continue for ever before thee; for thou, O Lord Jehovah, hast spoken it: and with thy blessing let the house of thy servant be blessed for ever.

then Toi sent Joram his son unto king David, to salute him, and to bless him, because he had fought against Hadadezer and smitten him: for Hadadezer had wars with Toi. And Joram brought with him vessels of silver, and vessels of gold, and vessels of brass:

and David said unto the Gibeonites, What shall I do for you? and wherewith shall I make atonement, that ye may bless the inheritance of Jehovah?
